摘　　要：稻田固碳减排是我国实现碳中和的重要技术措施。为推动我国寒地水稻绿色、低碳、可持续发展,本文在了解我国寒地稻田系统2010-2019年碳排放及碳中和概况的基础上,探索我国寒地稻田系统固碳减排的对策,包括选用氮素利用率高的水稻品种、适宜的水分管理模式、综合考虑有机肥和氮肥的施用种类及比例、翻耕和旋耕每年交替的轮耕制度等。并提出今后寒地稻田固碳减排应重点考虑加强寒地稻田温室气体产生、排放的机理及影响因素研究,强化寒地稻田温室气体排放量的准确估算,通过多学科交叉融合研究寒地稻田温室气体排放。Carbon sequestration and emission reduction in paddy field is an important technical measure to achieve carbon neutrality in China.In order to promote the green,low-carbon and sustainable development of cold rice in China,based on the carbon emission and carbon neutrality profiles of cold rice field system was analyzed in China from 2010 to 2019,the countermeasures of carbon sequestration and emission reduction of cold rice field system were explored in China,including the selection of rice varieties with high nitrogen use efficiency,appropriate water regime management,comprehensive consideration of the application types and proportion of organic fertilizer and nitrogen fertilizer,the rotation system of annual alternation of ploughing and rotary tillage,etc.In the future,it was proposed that the carbon sequestration and emission reduction of cold paddy fields should focus on strengthening the research on the mechanism and influencing factors of greenhouse gas generation and emission of cold paddy fields,strengthening the accurate estimation of greenhouse gas emission of cold paddy fields,and studying the greenhouse gas emission of cold paddy fields through interdisciplinary integration.
